Missing audit log for admin configuration

[Xan4x]

Hello,

When we create a user or a role for example, we don't have information of what was created in the log.

For example, request of the creation of a user:
` $ curl -k -X 'POST'
'https://127.0.0.1:8888/@warpgate/admin/api/users'
-H 'accept: application/json; charset=utf-8'
-H 'Content-Type: application/json; charset=utf-8'
-H 'X-Warpgate-Token: XXXXX'
-d '{
"username": "test-user"
}'

Answer:
{"credential_policy":{"http":null,"mysql":null,"postgres":null,"ssh":null},"id":"d55f25b5-3b2a-40c3-99e8-1aaabce05c56","username":"test-user"}`

On the log, we only found "Created" with the admin/api/users, so we understand that a user is created

`13:22:13  INFO HTTP: Request method=POST url=https://127.0.0.1:8888/@warpgate/admin/api/users status=201 Created client_ip=172.19.0.1`

But some information is missing:

• we don't have information of which user or API token used to create this user.
• we don't have information about the user created : API response is not available

Is it possible to add:

• on the log, the user name or API-token name used by the API
• on the warpgate product new kind of logs: "audit logs" with API request/responses for example and and make them available on the warpgate admin page for example?
